Rh Gold and silver fishes, though originally natives of China and Japan, yet are become so well reconciled to our climate as to thrive and multiply very fast in our ponds and stews. Linnæus ranks this species of fish under the genus of Cyprinus, or carp, and calls it Cyprinus auratus.

Some people exhibit this sort of fish in a very fanciful way; for they cause a glass bowl to be blown with a large hollow space within, that does not communicate with it.

I know a small pond which is kept warm by waste water from the boilers of an adjoining paper-mill, where these fish are in incredible numbers for so small a space, and grow to four or five pounds in weight.

LETTER LIV. , October 10th, 1781. ,—I think I have observed before that much of the most considerable part of the house-martins withdraw from hence about the first week in October; but that some, the latter broods I am now convinced, linger on till towards the middle of that month; and that at times, once perhaps in two or three years,
